MACHINE ELEMENT.

Specification of Letters Patent. 7 Paftaiitedl An. 24, 1915.

Application filed December 1, 1913. Serial No. 803,979.

T 0 all whom it may concern Be it known that I, NonToN M. BRowN, a citizen of the United States, and a resi dent of the city of Aurora, county of Kane and State of Illinois, have invented a New and Useful Machine Element, of which the following is a specification.

My invention relates to ensilage cutting machines, and more specifically to the feeding mechanism thereof. a

In machines of this type employing in the feeding mechanism thereof floating feed rollers, it has been found that the floating feed rollers, during operation of the machine, are not maintained in parallelism with the feeding elements with which the same cooperate and that by reason of the movement or tilting of said floating feed rollers out of parallelism with the feeding elements cooperatin therewith, the gears through the medium of which said floating feed rollers are driven bind with the gears which mesh with said first mentioned gears.

It is the object of this invention to provide means for maintaining the floating feed rollers, above mentioned, in constant parallelism with the feeding elements coiipcrating therewith during the vibratory or floating movement of said rollers, as when the ensilage machine is in operation, and to thereby obviate the objection or gear binding trouble above referred to.

A further object is the production of mechanism as mentioned, which will be simple and economical in construction, and eiflcient in use.

Other objects will appear hereinafter.

lVith these objects in view, the invention consists in the combinations and arrangements of parts hereinafter described and claimed.

The invention will be best understood by reference to the accompanying drawing forming apart of this specification, and in which,

Figure 1 is a fragmentary side elevation of an ensilage cutting machine equipped with mechanism embodying my invention, and Fig. 2 is a vertical transverse section taken on substantially line woc of Fig. 1.

The preferred form of construction as illustrated in the drawing comprises feeding rollers carried by shafts 1 and 1 which are mounted for free vertical or floating movement in arcual slots 2 and 2 respectively, provided in opposite sides of the frame or body 3. of the ensilage machine. The respective ends of the shafts 1 and 1 are mounted in bearings provided in the free ends of arms at and 5 which are pivoted at 6, the point 6 being the center of curvature of the slots 2 and 2, as will be readily understood.

In order to maintain the shafts 1 and 1 in horizontal position and hence in fixed parallelism with the feeding elements with which the same cooperate, crank shafts 7 are provided mounted in suitable bearings S secured to the frame of the machine as shown. Each of the crank shafts 7 is provided with two cranks 9 which are formed at the ends of said shafts, said cranks being connected by links 10 with the respective ends of shafts 1 and l, as shown. With this arrangement, it will be seen, that the respective ends of each of the shafts 1 and 1 will be connected together so as to move uniformly or in unison, whereby said shafts will be constantly maintained in horizontal position and therefore parallel with the feeding elements with which the same cooperate. This being so, the objectionable binding of the gears through the medium of which said shafts 1 and 1 are driven will be obviated, thereby conducing to smoother and lighter running of the machine.

While I have illustrated and described the preferred form of construction for carrying my invention into effect, this is capable of variations and modifications without departing from the spirit of the inven tion. I, therefore, do not wish to be limited to the precise details of construction set forth, but desire to avail myself of such variations and modifications as come within the scope of the appended claims.

Having described my invention what I claim as new and desire to secure by Letters Patent is:

1. In mechanism of the character described, the combination of a pair of cooperating parallel rotatable elements, one of said elements being mounted for free movement toward and from the other; means for maintaining said movable element in parallelism with the other of said elements, said means comprising a rockingly mounted shaft having two cranks; and links connecting the ends of said movable element with said cranks, substantiallyas described.
